JOSEPH B. DE LEEY, OE NEw YORK, N. Y.

VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 565,471, dated August11 1896.

Application led February 12, 1896. Serial No. 579,007. (No model.)

To all whom it may concern,.-

Be it known that I, JOSEPH B. DE LRY, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Vapor-Burners, ofwhich the following is a full, clear, and exact description.

This invention relates to burners for that class of lamps in which avolatile hydrocarbon is used as a fuel and in which the heat of theiiame is utilized to generate the vapor which is supplied to the burner.

This burner was designed especially to be used upon the lamp describedin the application of Hanorah Moran, led January 25, 1896, Serial No.576,760; but the invention is not confined to this lamp.

The obj ect of this invention is to provide a combined burner andvapor-generator which shall be simple in construction and efficient inoperation.

The invention consists of the construction hereinafter described andclaimed.

Referring to the accompanying drawings, Figure l represents a sideelevation of the lamp. Fig. 2 is a perspective view of the burner, andFig. 3 is a cross-section ofthe same.

The lamp proper consists of a reservoir A, which is to contain gasoleneor other volatile hydrocarbon. The lamp will have a wick leading fromthe reservoir through one of the handles a, which will be tubular forthat purpose, the wick ending at the upper end of the handle, where theburner is connected.

b represents the burner, the construction of which constitutes theinvention herein described. The burner is shown in Figs. 2 and 3,wherein it will be seen that it has a ridge h along its upper edge and alongitudinal groove b2 each side of the ridge and a short distance belowit. The burner is hollow and provided with a nipple b8 or other means ofconnection with the upper end of handle a.

In the lower corner of each of the grooves b2 a row of perforations isformed, extending into the burner and forming the escape-pas sages forthe vapor. These perforations are made vertically to direct the vapor asmuch as possible against the upper edges of the groove, so that when thelamp is burning the ridge b will become highly heated and the heat willbe conducted throughout the entire burner. In the chamber of the burnerI place a piece of wire-gauze, (represented by c.) This is in the formof a cylinder and is to distribute the gas or vapor generatedin thechamber evenly to the several perforations and to form a kind of cushionfor the vapor, preventing it from passing out too freely and tending tokeep the flame steady. The groove b2 may be located on one or both sidesof the ridge; but I prefer to have them on both sides, as shown.

The lamp is lighted by holding a lighted match under the burner for ashort time to transform the hydrocarbon contained in the end of the wickadjacent to the burner into a vapor. The vapor soon forces out throughthe perforations in the groove b2 and is then ignited. Therefore theflame itself heats the burner by reason of its contact with the ridge ofmetal between the grooves. The chamber thus being always hot vaporizesthe fuel and automatically supplies a constant flow of gas to the name.

Having thus described my invention, I claiml. A gas or vapor burnerprovided with a horizontal closed ridge and having sides eX- tendingobliquely downward from said ridge, and a groove or grooves located insaid oblique sides, through which the gas or vapor flows, substantiallyas described.

2. A gas or vapor burner provided with a horizontal ridge, a grooveparallel to and below the ridge, and a series of perforations for theescape of gas located in the lower corner of Said groove, and at rightangles thereto, substantially as described.

In testimony whereof I subscribe my signature in presence of twowitnesses.
